Energy Flow Through Ecosystems
Middle or high school environmental studies classes will learn much from this presentation on energy in ecosystems. It covers the foundational topics of trophic levels, food webs, and nutrient cycles using informational text and...
Curated OER
Trophic Pyramids and Levels
The bulk of this lesson involves the construction of both an aquatic and a terrestrial ecosystem in which to observe trophic relationships. Detailed directions are provided, as well as discussion questions, and assessment activities....
Curated OER
Trophic Ecology of Humans
students analyze the place of humans among the tropic levels by observing what we eat. They calculate the caloric content of several foods commonly eaten by humans and calculate the total energy cost to grow, process, transport, store...
Curated OER
Community Ecology
Chart ecological community interactions and answer questions about niche, defenses, trophic structure, and succession. This community ecology instructional activity provides a general overview of the interactions that occur among...

Food Webs, Energy Flow, Carbon Cycle, and Trophic Pyramids
The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...
Curated OER
Forest Ecosystem
Students become familiar with the temperate rainforest. In this forest ecosystem lesson, students identify the producers, consumers and decomposers in the forest ecosystem. Students sort cards and identify the trophic level of the...

Lesson 4: Gorongosa's Food Webs
Who eats who in the savannas of Africa? Explore trophic levels with part four of an eight-part series of lessons focused around Gorongosa National Park. After young explorers identify animals using trailcam images, they construct a food...

Construction of Food Chains and Tracing Energy Changes
If you need a few basic activities for teaching food chains to your emerging ecologists, here they are. Three sheets of organism cards are included for learners to cut out and arrange according to trophic relationships. To make the most...

Modeling Trophic Cascades
In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...
Curated OER
it's Lonely At The Top
Learners explore the differnences between food producers in food webs and food consumers in food chains. Behavioral choices of primary and secondary consumers such as herbivores, vegetarians, carnivors, and omnivors are analyzed.

Pterosaurs: The Card Game
Piecing together the past is a challenging endeavor. Learners get a taste of that challenge as they play a game that incorporates several components such as trophic levels, geological time periods, and catastrophic events. Pairs work to...
Curated OER
Trophic Ecology of Humans
Young scholars analyze the trophic level of humans by first calculating the kilocalories in own their lunch. They then calulate the kilocalories in a wide variety of foods found in grocery stores and compare the kilocalories needed to...
Curated OER
Lessons: Food Web
Students use an interactive web-based food web game to gain familiarity with tropic levels and interactions. They already understand that in an ecosystem there are four basic tropic levels: producers, primary consumers, secondary...
Curated OER
Food Webs
Pupils recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.

How Does Energy Cycle in Ecosystems?
In this energy cycle worksheet, students will write in examples for each trophic level in an energy cycle: top, middle, and lowest levels.
Curated OER
Ecological Pyramids
Students apply the ecological pyramids of numbers and biomass with an activity using topographic maps. In this trophic level lesson, students work in groups using a topographic map to determine the number of organisms that can live in an...
Curated OER
Heat 1
For this heat worksheet, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This worksheet has 10 fill in the blank, 5...
Curated OER
Life or Death Food Chain Decision
High schoolers discuss how energy is transferred to different trophic levels. In this biology lesson, students solve a theoretical problem and debate on a solution. They explain how energy is lost during cellular respiration.

Everybody Needs a Little Sunshine
Three activities introduce upper elementary ecologists to photosynthesis and food webs. In the first, an experiment is set up to determine how plants respond to different types of light. In the second, they connect organism cards with...
Curated OER
Entering The Twilight Zone
In this lesson sixth grade young scholars get into groups and research a given ocean habitat. The major features of cold-seep communities are the objective but plenty information is given about other habitats which could be assigned to...
